Chinese Foreign Minister

Wang Yi

on Wednesday warned his Philippine counterpart that Manila would “bear the bitter consequences” if it tried to provoke Beijing with the help of other countries.

Wang made the remark as he lodged a “strong protest” during talks with Theresa Lazaro, the Philippines’ top diplomat, in Manila over what he called an “aggressive act of ramming a Chinese law enforcement vessel” at a disputed reef in the

South China Sea

on Monday.

It was the third day Beijing has protested over

the confrontation

at Second Thomas Shoal involving a Chinese coastguard vessel and two Philippine Navy rubber boats.

Relations have been tense between

Beijing and Manila

in recent years, with frequent clashes in disputed waters of the South China Sea.

Beijing has also been on high alert as Manila has sought closer defence and security ties with Washington and Tokyo. The Philippines is considered a vital link in the “first island chain” that the United States sees as a way to contain Chinese naval expansion.
